Improvement in speeders

IMPROVEMENT IN SPEEDES..

Specification forming part of Letters Patent N o. 139,603, dated J une 3, 1873; application Vtiled October 16, 1872.

To all whom it may concern:

Be it known that I, GEORGE W. OLNEY, of Lincoln, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Speeders.

Myinvention relates to that class of speeders in which reciprocating live-spindles and bow-fliers are employed; and it consists in the novel combination therewith ot' a driven bolster, so arranged with relation to the spindle that the latter will be steadily'driven by` it, while freely traversing with the copping rail and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear and true description of a bowi flier and spindle embodying my improvement.

Referring to the drawings, Figure 1 repre sents, in front view, a spindle with the driven bolster. Fig. 2 represents the same in vertical v section. i

A denotes the usual stationary bottom rail; B denotes the usual stationary top rail; and C denotes the usual traversing or copping rail. D denotes a bow-dier of the usual form, arranged to be driven by bevel-gearing, in this `instance, and mounted in fixed bearings located'ou the top rail in a manner not new. E denotes a reciprocating live-spindle, arranged to carry the bobbin within the range ofthe dier in the usual manner. The spindle is supported by a collar, d, secured by a set-screw to the spindle, and a forked arm, e, attached to and projecting outward toward the front from the copping rail. F denotes a driven bolster. It is suspended in accurately-tted bea-rings f, which are secured to the bottom rail A. It is provided at its lower end with a horizontal driving-gear, which is arranged with proper relatiouto a vertical gear in the usual manner. A shoulder at its upper end, resting in the top of the bearing f, and the upper surface of the gear being in contact with the lower end of the bearing, prevents any vertical movement of the bolster. The bolster is traversed for nearly its whole length by a straight slot, y. The spindle E is provided with a radial stud, h, which projects into and loosely occupies the slot g in such a manner that the bolster, when revolved, will carry the spindle with it, and

at the same time `to freely allow the spindle to rise and fall within it when actuated by the copping rail.

It will be observed that the bolster F and its driving-gear are rigidly united, andfare, therefore, so far as operation and effect are concerned, the same as if a longnecked gear were employed with sufticientbeariug to not only steady the spindle within its eye, but to steady itself in its bearing. The same results will accrue it' the spindle be slotted and the stud be made to project from the bolster into said slot, although the method ot' connection shown and described is preferable to any other known to me.

A spindle mounted and driven as described is peculiarlyT steady in its movement, and practically admits of the non-'use of the long upper tubular bolster, which quite recently has been generally deemedessential for producing good results with a high rate of speed. As far as relates to economy in the structure, in the consumption of oil, in durability and non-liability to get out ot' order, I know of none with which my improved Speeder will compare unfair'orably. No greater consumption of power is requisite to drive my Speeder tlfau is necessary for the most approved spindles ofits class nowin use, and the speed readily attaiied, and the practical results in the spinning accomplished, are fully equal, `in my opinion, to any of the most generally ap` proved Speeders.

i In this connection I have represented the traverse or copping rail as located between the bottom and top rails, and sustaining the spindles a-t a point about midway between their tips and bases. The said traverse rail is located, as shown, with a range ot' action between the two stationary rails, and by this arrangement great steadiness of movement is secured, as it traverses between two fixed portions of the frame of the machine.

I am aware that ordinary gears with splines have been combined with slotted spindlesr and that long-necked gears have been employed in a similar connection, as in machines known as Mayoxs Speeders 5 but I am not aware that prior to my invention a reciprocating `Speeder-spindle was ever driven by contact with a driven bolster, or by a gear so constructed and arranged asv to` practically perform the function ot a bolster while the spindle moved up and down within the eye of tue gear. In the so-called Mayor speeder,

' aforesaid, the long-necked gear loosely embraces the spindle, and its bearing or box is so located, and in practice `is so fitted, that the neck of the gear cannot practicallyY perform the functions of a bolster.

I therefore claim as new and desire to secure by Letters Patent- The combination, with a vertically recipro-
